The main objectives of weld inspection and quality control are preventing welding issues by taking rehabilitative activities beforehand in the production stage, and making sure the quality of the end product. For instance, a timely assessment might protect against a whole set of negative welds resulting from bad joint cleanliness or fit-up.




Often, it might be required to check the WPS certification by performing tests on weld discount coupons (examination items). Validating the base metal and welding consumables conformity with the relevant specifications. Checking for joint tidiness and proper fit-up. Making certain that the joint layout and weld preparation is compliant with the WPS and applicable welding criteria (ASME, AWS, API).




Sometimes, pre-welding inspection may find irregularities that are within code constraints but might pose an issue at a later stage in manufacturing. That's why it's essential for the welding examiner to be acquainted with the entire production process and to be experienced with the bonded devices. Evaluation during the welding process is necessary for spotting the weld defects and protecting against a wrong welding approach from triggering huge weld denials throughout the whole job.

Another example would certainly be not evaluating for too much distortion, which would cause weld being rejected and pricey rework if done on costly equipment like heat exchangers, distillation columns, and central heating boilers. A few of the conventional quality assurance checks during welding are: Confirmation of pre-heat and interpass temperatures and making sure that they are within restrictions defined in the WPS.


Confirm the protecting gas and flux are as advised in the WPS. Reviewing sequencing treatments for distortion control. Tack weld quality assessment. Confirming a proper fit-up prior to welding. Checking the origin pass and successive weld passes. Inspecting the root condition before welding the opposite. Ensuring that slag, silica, and other impurities are removed between passes.
